Page 7: Mounting
MOUNTING The unit is designed to be mounted with a gasket providing a water tight seal. Two mounting brackets are provided to secure the unit to the panel. A panel less than .1" may distort if the clamps are screwed too tightly. Slide the body of the unit through the rubber gasket. -
Page 8: Wiring
WIRING The rear terminal contains 12 screw terminals for connecting #14 to #28 gauge wire. The unit is controlled by a microprocessor and, therefore, an electrically "noisy" environment could cause operating problems. The input power line should not be common to power lines for motors, pumps, contactors, etc. The unit is designed to be immune from line or RF voltage interference. - Page 9 WIRING (continued) AC / DC Power Connections NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has been designed with an isolated AC input. Thus, polarity is not a concern for the AC input. Connect AC power to pins 11 and 12. The chassis is plastic, therefore earth ground is not used.

Page 15: Calculating Scale Factors
CALCULATING SCALE FACTORS The unit has a programmable scale factor to scale the input pulses. It is a 5 digit , floating decimal divider factor. The fac t or to enter is the number of pulses per the desired unit of measurement. The factor ranges from 0.0001 to 99999. Scale factor calculations are simple. -
